Love it! Can’t wait to buy a second one!
Size: Left Facing, Size: Left Facing
Worth every penny!! This rack is pricy, but it’s awesome. Definitely wish the price was a little better, but I still plan on buying a second one to fit more of my spices. Super easy to install and the glide feature is really smooth. Bottles and lids are quality material and overall really pretty design. Love that it comes with TONS of spice label options for every spice you could imagine! Fit in my standard depth cabinet that is 12” deep (and I have inset cabinet doors and there was still plenty of room for it). You can easily pull it out and read the labels.

Aesthetic & Functional
Size: Left Facing
Good use of vertical space. It feels very secure and sturdy once mounted. It comes with everything you need, there’s a label for every spice and variation of that spice you can think of (different labels for the same spice but whole vs ground) and plenty of jars, with a few extra. Very well thought out. The tops were also standard enough to fit some of my existing spice jars so I didn’t even need to transfer those ones I just swapped lids and/or added a label. I previously had a different pull out spice rack with two flat shelves but it was a pain to find a specific spice without moving some out of the way, and it held maybe half as many jars as this one. This is an easy organization project that will free up a ton of horizontal cabinet space and makes finding spices while cooking significantly easier. If you do want to use your existing jars, make sure they have a flat side, as cylinder shaped jars roll around a bit when you slide it out. I just transferred my spices with round jars into the provided jars so wasn’t an issue for me! Really great value, especially considering how much the kit comes with!

Spicy racks
Item Package Quantity: 2, Item Package Quantity: 2
I bought these as I needed to organize my spice cabinet. I was using a lazy Suzanne and the spices kept falling off them. These fit perfectly in the cabinet,I attached them using the command Velcro stickers that come off easy. I am in an apartment. They are strong enough to allow the shelves to slide out.

Great product
Item Package Quantity: 2
Fit perfectly in my cabinet and gives me the room and accessibility I was looking for. Being 5'4 and needing a step stool to reach my spices above the microwave was pretty annoying. They are solid, quality racks. Very easy to assemble and adheres well to the cabinet.

Great Quality, but Check Cabinet Height Carefully
Item Package Quantity: 2
I am so, so sad these iSpecle Pull Out Spice Racks did not fit in my kitchen cabinets. I thought I had checked, but the most my cabinets can take with the nonadjustable shelves is 9", and these are a little over 9.5" tall at the metal rack side. They may not fit where I intended to use them, but they appear to be good quality and really help with organization. They look nice and slide in and out well, so I fully intend to find another way to use them. Maybe under the bathroom sink where smaller items also like to cluster.
